ReplaceMissingTeethtoPreventOtherTeethFromMovingOutofPlace

Although your teeth feel as if they’re rigidly set in the jawbone, they’re actually capable of movement. In fact, dynamic tooth movement is an essential mechanism in good dental function — it allows your teeth to adapt to changes brought on by age and other factors.

The periodontal ligament is a key component in this mechanism. This elastic tissue actually holds the teeth to the bone through tiny fibers that attach to the tooth root on one side of the ligament and to the jawbone on the other. The teeth move within the ligament to maintain contact with both adjacent and opposing teeth in response to changes like the normal wear that occurs due to aging.

This is a primary reason why a missing tooth should be replaced by an artificial one as soon as possible. Because of the tendency just described, teeth next to the space left by the missing tooth will begin to move (or drift) into the space at an accelerated rate. The end result is teeth out of their normal position and range, which could seriously disrupt their normal function as well as adversely affect your appearance.

This is especially important for back teeth. Because they’re not easily visible to others when we open our mouths, many people will forgo replacement when they’re lost. But missing back teeth can set off a chain reaction of movement that could eventually hinder jaw function.

The best option for a tooth replacement is a dental implant. Life-like and durable, dental implants encourage bone growth at the implant site and adjacent teeth will respond to it as they would a natural tooth. If an implant isn’t feasible, then a fixed bridge is also a viable replacement option that will prevent drift. As a result, tooth movement should continue normally with no adverse effects on function.

If you’ve lost teeth or are about to undergo tooth extraction, it’s in your other teeth’s best interest to consider a permanent replacement. A new implant or bridge will vastly improve your smile and prevent more serious problems in the future.

MarthaStewartSharesToothTouch-UpSecrets

Here’s a quick quiz: What recent activity did domestic guru Martha Stewart share via social media for the first time? Need a hint? Was she following the lead of other celebrities like rapper 50 Cent (AKA Curtis James Jackson III), actress Demi Moore and country music star LeAnn Rimes?

Give up? The answer is… she live-tweeted her visit to the dentist! Not only that, she also posted pictures of her mouth as she was undergoing an in-office whitening procedure.

Now, we understand that some might feel they don’t need to see close-ups of Stewart’s teeth under treatment. But we have to admire her for not trying to hide the fact that she’s had the same procedure that has benefited so many people, whether famous or not. Plus, her pictures actually provide a good illustration of how the treatment works.

In-office whitening treatments are the fastest way to brighten up your smile. In a single one-hour visit, your teeth can be lightened by three to eight shades — and that's a big difference! How can we achieve such dramatic results? When you’re under our direct supervision in an office setting, we can use the most concentrated bleach solutions safely and effectively. You can get similar results with custom-made trays and take-home lightening solutions we can prepare for you, but then the process will take longer.

If you look closely at her photos, you’ll see that Stewart’s lips, gums, and face are covered up to prevent any contact with the bleaching solution. She’s also wearing protective eyewear, which not only keeps chemicals away, but also guards her eyes against strong lights, which are sometimes used in conjunction with bleach. When we perform in-office whitening procedures, we use safeguards like these for all of our patients — not just celebrities!

We also perform a complete oral examination before starting any whitening procedure, to be sure you don’t have any underlying conditions that need to be treated before teeth whitening begins. That’s something you just can’t get from an over-the counter whitening product.

Teeth whitening is an effective and affordable way to give your smile a quick boost. But whether you decide to live-tweet your procedure — or keep your fans guessing about why your smile looks so good all of a sudden — that’s up to you.

If you would like more information about the teeth whitening, please contact us or schedule an appointment for a consultation. You can learn more in the Dear Doctor magazine articles “Teeth Whitening” and “Important Teeth Whitening Questions Answered.”

Dental-FriendlyChewingGumcanbeBeneficialtoYourOralHealth

Chewing gum, so much a part of modern culture, actually has ancient roots — humans have been chewing some form of it for thousands of years. While gum chewing is a benign habit for the most part, it does raise some dental health concerns.

The good news for jaw function is that chewing gum is unlikely to cause any long-term problems for your joints if you respond to your body’s warning signals. Our joints, muscles and associated nerves have a built-in mechanism of fatigue and pain signaling to help us avoid overuse. Furthermore, the action of chewing stimulates the production and release of saliva. Among saliva’s many beneficial properties is its ability to neutralize acid, which can soften and erode tooth enamel. It also strengthens enamel by restoring some of the calcium and other minerals lost from acid.

That doesn’t mean, however, that the physical act of chewing gum isn’t without risks. Chewing gum “exercises” your jaw muscles and makes them stronger, so they’re able to deliver more force to your teeth. This could lead to future tooth mobility and excessive wear. It’s important then that you don’t chew gum excessively to avoid this kind of damage to your teeth.

Unfortunately, there’s more bad news involving a key ingredient in many brands. Many manufacturers use sugar (sucrose) to sweeten their product, which is a major part of its appeal. Sugar, however, is a prime food source for oral bacteria responsible for tooth decay. The prolonged presence of sugar in the mouth when we chew gum can negate the beneficial effects of increased saliva.

A sweetener called xylitol, though, could be the answer to “having your gum and chewing it too.” This alcohol-based sugar (which, by the way, has almost half the calories of table sugar) has the opposite effect on bacteria — rather than becoming a food source it actually inhibits bacterial growth. Studies have even shown that products like chewing gum, mints or candy sweetened with xylitol can contribute significantly to a reduction in dental caries (cavities) caused by decay.

The better news: you don’t have to give up chewing gum for the sake of your teeth — just be sure to choose products with dental-friendly ingredients and don’t chew excessively. You’ll not only reduce the risks of tooth decay and damage, you’ll also promote a healthier environment in your mouth.

If you would like more information on chewing gum and its effects on dental health, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine articles “Chewing Gum” and “Xylitol in Chewing Gum.”

AWake-UpCallinMajorLeagueBaseball

What would it take to get you to give up tobacco? For major league baseball player Addison Reed, it took the death of his former coach, Tony Gwynn. Gwynn, a Hall-of-Famer who played for the San Diego Padres in addition to coaching at San Diego State, was just 54 years old when he died of oral cancer. As soon as Reed heard the sad news, the Arizona Diamondbacks’ relief pitcher says he knew what he needed to do: He took every can of smokeless tobacco he owned and dumped them all in the trash.

“It’s just become a habit, a really bad habit,” Reed told an interviewer at MLB.com. “It was something I always told myself I would quit.” But quitting took him many years — in fact, Reed admitted that he first started using smokeless tobacco as a junior in high school.

People begin using tobacco — in the form of cigarettes, cigars, pipes, or smokeless types (snuff, chewing tobacco, or dip) — for a variety of reasons. One major draw is that they see others doing it. And, while smoking is prohibited in most all Major League venues, the use of smokeless tobacco has remained fairly widespread.

Smokeless tobacco isn’t a safe alternative to cigarettes. According to the National Cancer Institute, it contains 28 carcinogenic agents. It increases the risk not only for oral and pancreatic cancer, but also for heart disease, gum disease, and many other oral problems. It’s also addictive, containing anywhere from 3.4 to 39.7 milligrams of nicotine per gram of tobacco — and its use has been on the rise among young adults.

But now the tide may be turning. After Addison Reed’s announcement, his former college teammate Stephen Strasburg (now a pitcher for the Washington Nationals) resolved that he, too, would give up tobacco. “[The] bottom line is, I want to be around for my family,” said Strasburg. Mets left-hander Josh Edgin has vowed to try quitting as well. It’s even possible that Major League Baseball will further restrict the use of smokeless tobacco at games.

What does this mean for you? It may just be the opportunity you’ve been waiting for… to stop using tobacco. Dentists have seen how quickly oral cancer can do its devastating work — and we can help you when you’re ready to quit. The next time you come in for a checkup, ask us how. Your teeth and gums will thank you — and your family will too.

FrequentlyAskedQuestionsaboutFixedDentures

Q: Is there much of a difference between fixed and removable dentures?
A: There’s a BIG difference! Removable dentures are the type your grandparents might have had — and possibly their grandparents, too. They work well enough after you get used to them, but there’s always the issue of slippage, poor fit, limited function… and potential embarrassment. Modern fixed dentures, however, get their stability from today’s state-of-the-art system for tooth replacement: dental implants. They won’t loosen or slip, they function and “feel” like your own natural teeth, and they can last for years and years to come.

Q: How are fixed dentures supported?
A: Each arch (set of teeth comprising the top or bottom jaw) of a fixed denture is anchored into the jaw bone by four or more dental implants. These small screw-like devices, made of titanium metal, are placed into the jawbone in a minor surgical procedure. Once set in place, they remain permanently attached by both mechanical forces and osseointegration — the process in which living bone cells actually become fused with the metal implants themselves.

Q: What is the procedure for getting dental implants like?
A: Before having any work done, you will receive a thorough examination and have a set of diagnostic images made. Implant surgery is normally performed in the dental office, using local anesthesia or conscious sedation. If any failing teeth must be extracted (removed), that will be done first. Next, small openings are made in the gums and the jawbone, and the implants are placed in precise locations. Sometimes, a set of temporary teeth can be attached to the implants immediately; other times, the implants will be allowed to heal for a period of time.

Q: Besides added stability, are there other advantages to fixed dentures?
A: Yes! As they become integrated in the jaw, dental implants actually help preserve the quantity and quality of bone in the jaw; removable dentures, on the other hand, decrease bone quantity and quality. This is important because the jawbone plays a vital role in supporting facial features like lips and cheeks. When the facial features lose support, it can make a person look prematurely aged. Also, people who wear removable dentures often have trouble eating “challenging” foods like raw fruits and vegetables (which are highly nutritious), and opt for softer, more processed (and less nutritious) foods. With fixed dentures, however, you can eat the foods you like.

Q: Aren't fixed dentures with dental implants more expensive?
A: Initially, the answer is yes — but in the long run, they may not be. Unlike removable dentures, which inevitably need to be re-lined or remade as the jawbone shrinks, fixed dentures can last for the rest of your life. They don’t require adhesives or creams, and you will never have to take them out at night and clean them. In fact, you can think of them as a long-term investment in yourself that pays off with a better quality of life!
